A newly designed multifunctional two-dimensional coordination polymer (2D CP) {[Cd(suc)(4-nvp)2]·2H2O} n , (1), (H2suc = succinic acid and 4-nvp = 4-(1-naphthylvinyl)pyridine) has been synthesized and characterized by X-ray crystallography. The solid-state structure of the compound 1 reveals the formation of three-dimensional supramolecular architecture via C–H···π and π···π stacking interactions. Interestingly, the supramolecular assembly of compound 1 exhibits electrical conductivity in the semiconducting nature. A deep insight into the electrical study of compound 1 carried out by dielectric characterization reveals the enhancement of conductivity upon light soaking. Thus, the compound has potential applicability in the fabrication optoelectronic devices. On the other hand, compound 1 shows sensing activity toward explosive nitroaromatic compounds (epNACs), which threatens devastating terror attacks ultimately responsible for massive loss of life. Besides, the nitroaromatic compound (NAC) 2,4,6-trinitrophenol (TNP) can enter inside the mammalian digestive cycle, wherein it gets metabolized into a mutagenic species, picramic acid, which causes health hazards. Compound 1 can detect TNP with the most acceptable fluorescence method. Together with its optoelectronic device fabrication and explosive sensing application, the synthesized material can be used as a potential candidate for sustainability.

“…To further understand the charge carrier mobilities of these materials, space charge limited current (SCLC) measurements were performed using both block copolymer supramolecules and the physical blend of PBA+NDI. , The film thicknesses of PS- b -P4VP(PBA+NDI) and the physical blend of PBA+NDI measured using the Dektak XT stylus profilometer were 2900 and 200 nm, respectively. Figure a shows the current versus voltage graph on log scale observed in the sandwich structure of ITO/(PBA+NDI)/Al, in which the region having a slope 2 is the SCLC region.…”

The hierarchical self-assembly of the charge-transfer (CT) complexes in the solid state is of paramount importance to dictate the performance of electronic devices. In this work, we describe a three-component hierarchical self-assembly approach to generate stable alternate donor–acceptor (D–A) assemblies within block copolymer microdomains by involving the supramolecular approach in self-assembly of block copolymers. So far, the assembly between a single small molecule and block copolymer was explored to obtain block copolymer supramolecules. Here we report block copolymer supramolecules composed of two small molecules (donor and acceptor) and polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP). 1-Pyrenebutyric acid (PBA, donor) forms hydrogen bonding with P4VP and aromatic interactions with naphthalene diimide (NDI, acceptor) to generate CT complexes within the block copolymer domains in the solid state. Using FTIR, SAXS, WAXS, TEM, UV/vis spectroscopy, and photoluminescence spectroscopy measurements, we demonstrate the formation of hierarchical structures and CT complexes between PBA and NDI. Space charge limited current analysis showed the enhanced charge carrier mobility in PS-b-P4VP (PBA+NDI) supramolecules compared to that in the physical blends of PBA+NDI. The organization of donor and acceptor molecules within the block copolymer microdomains opens up new insight into the area of electronic devices because of its advantages such as solution processability, controlled formation of hierarchical assemblies, and the CT interaction in the solid state.
