This paper introduces a co-design-based method for generating two-dimensional (2D) block patterns for physically disabled people with scoliosis, using three-dimensional (3D) virtual technology. A parameterization process is first performed on a scanned 3D body for creating a digitalized model of the human body, permitting simulation of the consumer's morphological shape with atypical physical deformations. Feature points of the human body for designing a garment block are discussed and classified with wearing ease for obtaining a desired fit effect based on the parameterized model. A basic garment block wire-frame aligned with body features is then established based on the defined feature points of the human body. Based on the deformed wireframe, a 3D expandable garment block is modeled. Customized 2D and 3D virtual garment prototyping tools are applied to create customized garment products based on the general concept of co-design by running the sequence Design–Display–Evaluation–Adjustment using the garment design process and design knowledge, which have already been applied to normal body shapes successfully. Through this process, the classical 2D garment design knowledge, especially 2D pattern design rules, will be modified according to the virtual garment evaluation procedure. The proposed method is validated and compared with the conventional block patternmaking methods in the virtual environment. The experimental results show that the proposed method is easier to implement and can generate garment patterns with satisfactory fit. Furthermore, the method can be used to create fit-ensured mass-customized apparel products (the top body type) for disabled people with scoliosis.

Locking-in the conformation of supramolecular assemblies provides an ew avenue to regulate the (opto)electronic properties of robust nanoscale objects.I nt he present contribution, we show that the covalent tethering of aperylene bisimide (PBI)-derived supramolecular polymer with amolecular locker enables the formation of al ocked superstructure equipped with emergent structure-function relationships.E xperiments that exploit variable-temperature ground-state electronic absorption spectroscopyu nambiguously demonstrate that the excitonic coupling between nearest neighboring units in the tethered superstructure is preserved at at emperature (371 K) where the pristine,n on-covalent assembly exists exclusively in am olecularly dissolved state.Aclose examination of the solid-state morphologies reveals that the locked superstructure engenders the formation of hierarchical 1D materials which are not achievable by unlocked assemblies.T o complement these structural attributes,wefurther demonstrate that covalentlytethering asupramolecular polymer built from PBI subunits enables the emergence of electronic properties not evidenced in non-covalent assemblies.U sing cyclic voltammetry experiments,t he elucidation of the potentiometric properties of the locked superstructure reveals a1 00-mV stabilization of the conduction band energy when compared to that recorded for the non-covalent assembly.

While the functionalization of silicon electrode surfaces with molecularly dissolved chromophores paves the way to create diverse redox-responsive interfaces, leveraging nanoscale objects derived from π-conjugated organic building blocks to modulate the electronic structures of Si hybrids remains vastly elusive. This study uncovers a redox-controlled stabilization effect exclusive to silicon electrodes functionalized with monolayers that are derived from perylene bisimide (PBI) nanoaggregates. For this class of n-type hybrid nanomaterials, we highlight that the cathodic potential required to inject negative charge carriers into the conduction band of the PBI monolayer can be reversibly stabilized by more than 375 mV through modulation of the maximum anodic potential (MAP) employed during the anodic cycle (i.e., +0.5 or +1.5 V vs Ag/AgCl). The magnitude of this redox-controlled stabilization effect is shown to be dictated by the structure–function relationships of the PBI nanoaggregates exploited to construct the monolayers on Si electrodes. Using a set of control experiments, we demonstrate that such a redox-controlled stabilization effect is not observed for monolayers derived from molecularly dissolved PBI precursors and for Si electrode precursors that feature a low density of anchoring groups. Supported by density functional theory calculations that highlight a significant structural reorganization of a model, partially p-doped PBI nanoaggregates, the data presented herein indicate that a MAP of +1.5 V versus Ag/AgCl is accompanied by a structural reorganization of the monolayers built exclusively from PBI π-aggregates. We propose that conformational perturbations engendered at a high anodic potential (+1.5 V) lead to the emergence of electronic states that further facilitate electron injections. The results uncovered herein establish a proof of principle that transferring the structure–function relationships of π-aggregates on inorganic electrodes delivers a powerful method to construct nanoscale semiconducting interfaces whose conduction band energies are redox-controlled in a reversible manner. This effect may establish the foundation for a new class of memory effect as the anodic potentials (write) dictate the current density at a given cathodic potential (read).

Controlling structure–function properties of hierarchical assemblies that feature stacks of π-conjugated building blocks represents an important challenge to engineer optoelectronic materials. In this regard, the development of new tools to navigate the free energy landscape of supramolecular assembly can lead to the creation of kinetically trapped superstructures equipped with emergent electronic properties. In the present contribution, we demonstrate that redox-assisted self-assembly of supramolecular polymers built from water-soluble perylene diimide enforces formation of superstructures with optoelectronic properties not manifested in parent assemblies. Leveraging on a theoretical model developed for H-aggregates in semiconducting polymers, free-exciton bandwidth has been calculated and increases by more than 30% in kinetically trapped superstructures (380 meV) when compared to initially prepared assemblies (290 meV). Electronic structure of intermediate assemblies is believed to perturb intermolecular interactions that regulate the conformation of initially prepared architectures. In addition to offering a means to modulate superstructure electronic properties, intermediate states can be further manipulated by thermal treatment to enable the formation of hierarchical nano-to-mesoscale materials. Investigation of their solid-state morphologies using atomic force microscopy reveals long aspect ratio nanowires spanning micro-to-mesoscale dimensions. Such morphological changes combined with novel electronic properties indicate that structure–function properties of supramolecular constructs can be modulated by redox-assisted self-assembly.
