AI Article Synopsis
- POS crystals made from 9-(4-sulfophenyl)anthracene (SPA) and triphenylmethylamine (TPMA) are able to hold fullerenes (C60 and C70) within them.
- When these crystals are not treated with fullerenes, they display blue fluorescence because of the presence of SPA.
- However, the addition of fullerenes causes this fluorescence to decrease or "quench" due to an electron transfer from SPA's excited state to the fullerenes.
Article Abstract
Porous organic salt (POS) crystals composed of 9-(4-sulfophenyl)anthracene (SPA) and triphenylmethylamine (TPMA) were impregnated with fullerenes (C60 and C70), which were arranged in one dimensional close contact. POS crystals of SPA and TPMA without fullerenes exhibit blue fluorescence due to SPA, whereas the fluorescence was quenched in POS with fullerenes due to electron transfer from the singlet excited state of SPA to fullerenes.
