Abstract

Low-molecular-weight organogels (LMWGs) with π-conjugated structures typically exhibit excellent photoluminescent properties and have significant potential in optoelectronic materials, sensing, and detection applications due to their large specific surface areas and high sensitivity. Conventional organogelators usually contain multiple amide bonds and long flexible chains to facilitate gelation. In contrast, non-conventional π-conjugated organogelators lack flexible chains, offering enhanced atomic economy. Furthermore, the suppression of non-radiative decay caused by the motion of flexible units could lead to higher emission efficiency. Notably, recent research has indicated that rigid chemical structures are essential for achieving ultra-long room-temperature phosphorescence (RTP) in organogels. This review highlights the structures, photoluminescent properties, and applications of non-conventional LMWGs, and discusses future perspectives and challenges in this emerging field.

期刊介绍: Materials Chemistry Frontiers focuses on the synthesis and chemistry of exciting new materials, and the development of improved fabrication techniques. Characterisation and fundamental studies that are of broad appeal are also welcome. This is the ideal home for studies of a significant nature that further the development of organic, inorganic, composite and nano-materials.
