摘要：
The pressure effect on intramolecular excimer formation of meso-bis[1-(2-pyrenyl)ethyl]ether dissolved in polyisoprene and in polyisobutylene has been investigated. The rate of conformational change of the probe is free-volume dependent. The results show that, at a given fractional free volume, obtained by changing either temperature or pressure, the probe has the same mobility.
