Abstract |
The highly sterically hindered meso-aryl BODIPY derivatives using ethyl 3,4-diethyl-1H-pyrrole-2-carboxylate or ethyl 3-ethyl-1H-pyrrole-2-carboxylate were synthesized and characterized. The steric hindrance resulting from the phenolic group in the meso-position and the ethyl groups at the 1,7 position affected the synthesis of dipyrromethanes as an intermediate as well as the UV absorption and fluorescence emission because of the constrained rotation of the aryl ring. The potential use of the meso-hydroxyphenyl BODIPY as a pH sensor was also shown by the pH-dependent fluorescence emissions. |
