Research on materials with pure organic room temperature phosphorescence (RTP) and their application as single-molecule white light emitters is a hot area relies the design of highly efficient RTP luminogens. Herein, facile strategy heavy-atom-participated anion-π+ interactions proposed to construct RTP-active salt compounds (1,2,3,4-tetraphenyloxazoliums different counterions). Those heavy-atom counterions (bromide iodide ions) exhibit outstanding due external heavy atom effect via...
Abstract Organic near-infrared room temperature phosphorescence materials have unparalleled advantages in bioimaging due to their excellent penetrability. However, limited by the energy gap law, (>650 nm) are very rare, moreover, lifetimes of these short. In this work, we obtained organic with long wavelengths (600/657–681/732 and (102–324 ms) for first time through guest-host doped strategy. The guest molecule has sufficient conjugation reduce lowest triplet level host assists exciton...
Recent years have witnessed the significant role of anion-π+ interactions in many areas, which potentially brings opportunity for development aggregation-induced emission (AIE) systems. Here, a new strategy that utilized to block detrimental π-π stacking was first proposed develop inherent-charged AIE Two AIE-active luminogens, namely, 1,2,3,4-tetraphenyloxazolium (TPO-P) and 2,3,5-triphenyloxazolium (TriPO-PN), were successfully synthesized. Comprehensive techniques such as single-crystal...
A series of organic host–guest materials with multifunctional luminescence were constructed. Four isoquinoline derivatives used as the guests, and benzophenone was host. The doped system exhibited excellent dual emission cyan fluorescence orange-yellow room-temperature phosphorescence, could be combined into almost pure white-light emission. Importantly, relative intensity fluorescence–phosphorescence adjusted by changing excitation wavelength, phosphorescence being significantly higher than...
Abstract A strategy is pioneered for achieving high-temperature phosphorescence using planar rigid molecules as guests and polymers host matrix.

The first example of a copper-catalyzed cascade reaction (2-aminophenyl)methanols with aldehydes using the combination cerium nitrate hexahydrate and ammonium chloride has been developed, leading to wide range 2-substituted quinazolines in moderate excellent yields. efficiency this transformation was demonstrated by compatibility functional groups. Thus, method represents convenient practical strategy for synthesis quinazoline derivatives.
