For organic opto-electronic materials, the macroscopic performance of molecular aggregates is not simply the combination of single molecules. The review focuses on the regulation of molecular aggregation to improve and generate luminescent properties. Mechanoluminescence (ML) and room-temperature phosphorescence (RTP) are emphasized as emission properties sensitive to molecular aggregates. The study also highlights the dynamic photophysical properties related to molecular motions and/or packing modes, as well as the adjustable molecular packing in different functional materials.
For the organic opto-electronic materials, the macroscopic performance of molecular aggregates is not just the simple overlay of single molecules, and in many cases, new properties can be generated by molecular uniting with particular packing modes, which are mainly determined by molecular structures of organic compounds. This review takes the photophysical properties as the key point, mainly discussing the regulation of molecular aggregation to improve and generate the interestingly luminescent proper-ties. Among them, mechanoluminescence (ML) and room-temperature phosphorescence (RTP) are emphasized as the typical emission property sensitive to molecular aggregates. Also, the dynamic photo -physical properties with the tiny variations in molecular motions and/or packing modes by various exter-nal stimuli are highlighted to investigate the possible relationship between opto-electronic performance and aggregated structures. Accordingly, the adjustable molecular packing in different fields is discussed in detail, including the internal mechanism, main effective factors, control methods, and preferred struc-tures in various functional materials, with the aim to afford the guideline to molecular design of organic opto-electronic materials, and promote their development from the internal to external.(c) 2022 Elsevier B.V.
