“…As the energy landscape is dependent on parameters such as concentration, temperature, and solvent composition, the equilibrium species may vary for a different set of conditions. However, the way in which it is reached has no influence on the final equilibrium structure . Any other species different from the thermodynamically stable one is a kinetic, non‐equilibrium structure.…”

Pathway complexity, hierarchical organization, out of equilibrium, and metastable or kinetically trapped species are common terms widely used in recent, high‐quality publications in the field of supramolecular polymers. Often, the terminologies used to describe the different self‐assembly pathways, the species involved, as well as their relationship and relative stability are not trivial. Different terms and classifications are commonly found in the literature, however, in many cases, without clear definitions or guidelines on how to use them and how to determine them experimentally. The aim of this Minireview is to classify, differentiate, and correlate the existing concepts with the help of recent literature reports to provide the reader with a general insight into thermodynamic and kinetic aspects of complex supramolecular polymerization processes. A good comprehension of these terms and concepts should contribute to the development of new complex, functional materials.

“…Da die Energielandschaft von Parametern wie Konzentration, Temperatur, Lösungsmittelzusammensetzung und weiteren abhängig ist, kann die Gleichgewichtsspezies für verschiedene Bedingungen variieren. Die Art und Weise, wie sie erreicht wird, hat jedoch keinen Einfluss auf die endgültige Gleichgewichtsstruktur . Jede andere Spezies, die sich von der thermodynamisch stabilen unterscheidet, ist eine kinetische, Nicht‐Equilibrium‐Struktur.…”

Pathway‐Complexity, hierarchische Organisation, Außer‐Equilibrium‐ und metastabile oder kinetisch gefangene Spezies sind Begriffe die in jüngsten, hochqualitativen Publikationen im Feld der supramolekularen Polymere häufig verwendet werden. Oftmals sind die Terminologien, die die verschiedenen Selbstassemblierungspfade, die beteiligten Spezies und deren Beziehung sowie relativen Stabilitäten zueinander beschreiben, nicht trivial. In der Literatur sind häufig verschiedene Begriffe und Klassifizierungen zu finden, in vielen Fällen jedoch ohne klare Definitionen oder Richtlinien wie sie zu benutzen sind oder wie sie experimentell unterschieden werden können. Ziel dieses Kurzaufsatzes ist es, die existierenden Konzepte mithilfe jüngster Literatur zu klassifizieren, differenzieren und zu korrelieren. Dadurch soll der Leser eine generelle Einsicht in thermodynamische und kinetische Aspekte komplexer supramolekularer Polymerisationsprozesse erhalten. Ein gutes Verständnis dieser Begriffe und Konzepte sollte dazu beitragen, neue, komplexe, funktionale Materialien zu erschaffen.

and fine chemical industries. [1][2][3][4][5][6] As a core element of microfluidic technology, high-performance fabrication of hollow microchannels with freeform geometries is crucial for further developing innovative microfluidic technology. In particular, extension of the microfluidic networks from widely used 2D to 3D configurations has now been considered as a promising scheme to enhance the performance of manipulation of fluids such as high-efficiency mixing, separation, and detection. [7][8][9][10][11] Fused silica is one of the widely used substrates for the microfluidic technology in laboratory research and industrial applications due to its high melting point, high chemical stability, low thermal expansion coefficient, wide transmission spectral range, and good biocompatibility. However, fabrication of freeform 3D hollow microchannels in fused silica is still difficult for current 2D fabrication techniques in terms of complex and tedious fabrication procedures, additional costs for aligning, stacking, and bonding steps. [12][13][14] Currently, one of the most representative 3D microfabrication techniques of fused silica is ultrashort pulse laser microfabrication. [15][16][17][18][19][20] A suspended hollow microchannel structure with a 3D controllable configuration can be fabricated in a way of either laser-assisted selective wet etching [21][22][23] or liquid-assisted laser ablation. [24][25][26] In addition, suspended hollow structures with 3D shapes and a high precision in fused silica can be fabricated by combining room-temperature casting and sacrificial template replication. [27] Meanwhile, 3D printing of glass materials emerging in recent years brings some new opportunities for scalable fabrication of freeform glass structures by either additive manufacturing strategies [28][29][30][31][32][33] or laser subtractive processing methods. [34][35][36] However, controllable formation of freeform hollow microchannel with arbitrary length encapsulated in 3D printed glass structures has not yet been demonstrated, which is highly desirable for high-infidelity manufacturing of artificial organs, on-chip construction of biomimetic microenvironments, [37][38][39][40][41] as well as enrichment of the functions of continuous-flow microreactors (e.g., seamless integration of customized functional module for temperature control and on-line spectrometer monitoring). [42,43] Especially, simultaneous fabrication of 3D embedded hollow microchannels with high aspect ratios and centimeter-scale glass objects with external arbitrary shapes on/in a single substrate still Large-scale microfluidic microsystems with complex 3D configurations are highly in demand by both fundamental research and industrial application, holding the potentials for fostering a wide range of innovative applications such as organ-on-a-chip as well as continuous-flow manufacturing. However, freeform fabrication of such systems remains challenging for current fabrication techniques in terms of fabrication resolution, flexibility, and achievable foo...
