研究目的
To greatly improve the emission efficiency of anthracene-o-carborane dyad based AIE luminogens through the linkage of anthracene-o-carborane units via tailored alkyl chains.
研究成果
The linkage of two luminescent building blocks together through proper alkyl chains greatly improves their emission efficiency without changing the emission color. The developed AIE luminogens exhibit impressive response to environmental stimuli of viscosity and temperature, making them useful for designing o-carborane-containing luminescent solid materials with stimuli-responsive properties.
研究不足
The study focuses on the synthesis and photophysical properties of specific anthracene-o-carborane derivatives. The generalizability of the findings to other systems and the practical applicability in optoelectronic devices require further investigation.
