| Abstract: | The synthesis of novel cavitands containing four fluorophores tert-butoxycarbonyl protected 2,2′-bis(furyl)benzidine (t-BOC FurylBz) or 5,5′-bis(4-aminophenyl)-2,2′-bifuryl (t-BOC PFDA)] and ionophoric functional groups on the upper rim is reported. The cavitands bearing the four fluorophores emit blue light photoluminescence. In particular, the cavitand containing PFDA moieties exhibits a high photoluminescence quantum yield. |
| Keywords: | cavitands fluorophores absorption photoluminescence blue light emit quantum yield receptor dual functionalities |
