Miracles of molecular uniting

Abstract

Union is strength". In the realm of organic molecules, the macroscopic performance of molecular aggregates is not just the simple overlay of single molecules, and in many cases, new properties can be created by molecular uniting with particular packing modes [1-4]. As to the organic emissive materials, various changes can be realized from single molecules to aggregates (Fig. 1), including the emerged bright emission, the varied emission color, the different emission forms, and the arisen new excitation processes.

Advanced technologies for the fabrication of MOF thin films

“…33,34 In a microfluidic device, the mixing of reagents only occurs through diffusion (following Fick's law), a feature that has paved the way to developing approaches for MOF thin film synthesis, and, in particular, for membrane fabrication. 18,34 The microfluidic synthesis of MOF membranes was first reported by Nair et al in 2014, 35 who developed a method, known as interfacial microfluidic membrane processing (IMMP), where polymeric hollow fibres were used to control the reaction-diffusion area during the synthesis of a prototypical MOF, i.e. zeolitic imidazolate framework-8 (ZIF-8, zinc 2-methylimidazolate).…”

“…Consequently, while the orientation and thickness of MOF thin films can be controlled to some extent with LbL methods, these protocols are time-consuming and labour intensive. 15,[18][19][20] (II) Electrically driven synthesis This approach consists of inducing the formation of MOFs on electrodes by means of electrochemical reactions or electrophoresis.…”

Aggregate Science: From Structures to Properties

“…In other words, AIE-related research has inspired us to propose that aggregate-level science should be considered independently from molecular science. [79][80][81][82][83] Aggregate-level studies have been carried out in parallel in other fields beyond PL. [84][85][86][87][88] For instance, in molecular biology, Figure 3.…”

Structural and process controls of AIEgens for NIR-II theranostics

“…Aggregation-induced emission (AIE) is an inventive uorescent technique and has the potential to address this issue. 4,[33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51] AIE illustrates a unique photophysical phenomenon where molecules are non-emissive in the discrete state because of active intramolecular motions, but emit energetically when aggregated due to the restriction of intramolecular motions (RIM). To drive emission to the NIR-II window, AIE luminogens (AIEgens) are designed as conjugated donor-acceptor (D-A) structures, where they are being twisted with each other (dihedral angle of q, Fig.…”
