Color Tuning of the Aggregation‐Induced Emission of Maleimide Dyes by Molecular Design and Morphology Control

Abstract: Aggregation-induced emission (AIE)-active maleimide dyes, namely, 2-p-toluidino-N-p-tolylmaleimide, 3-phenyl-2-toluidino-N-p-tolylmaleimide, 2-p-thiocresyl-3-p-toluidino-N-p-tolylmaleimide, and 2,3-dithiocresyl-N-arylmaleimides, were synthesized by facile synthetic procedures. The dyes show intense emission in the solid state, and emission colors were controlled from green (λmax =527 nm) to orange (λmax =609 nm) by varying the substituents at the 2- and 3-positions of the maleimide and the packing structures i… Show more

“…To investigate the effect of molecular motion on ACQ, DPh1 and DPh2 were dispersed in polystyrene( M n = 80,000,P DI = 2.6) films, and their optical properties were monitored.T he films including 1, 2,5,10,20,40,60,80, and 100 wt %o fDPh1 and DPh2 in polystyrene were prepared with as pin-coat methodf rom 40 mLC HCl 3 solution (1.0 10 À3 m of DPh1 and DPh2 in polystyrene). The resultsa re summarized in Figure S12 and Ta ble S1, Supporting Information.…”

“…[7] Additionally,A IE properties were also varied corresponding to drastic environmental changes such as freezing of matrices, [8] polarity alteration, [9] and addition of externalf orces. [10] These systems were applicable for sensitivee nvironmental sensors. Although various methodologies have been established so far, there is much room to explore precise control of molecular stacking and reflect externals timuli in the degree of stacking as optical property changes.…”

“…One promising strategy for obtaining solid‐state luminescent organic materials is to construct materials based on “element‐blocks”, which are defined as a minimum functional units composed of heteroatoms . In particular, by employing boron “element‐blocks” with AIE properties, a wide variety of optically functional materials have been developed . In addition to these luminescent boron complexes, it has also been reported that several compounds containing boron exhibit solid‐state emission without bulky substituents , .…”

“…To overcome ACQ and to obtain solid‐state luminescence, a class of compounds having aggregation‐induced emission (AIE), by which intense emission is observed only in the solid state and emission quenching is observed in solution, has attracted attention . By employing AIE‐active building blocks, various types of functional luminescent materials have been developed . Recently, we reported several AIE‐active boron complexes, and unique luminescent properties were found from boron pyridinoiminates BPI and FBPI (Scheme ) .…”
