Preparation of sterically constrained arylalkynes
摘要:
The preparation of a series of sterically constrained phenyleneethynylenes is described. Restricting the interannular rotation significantly narrows the lowest energy absorption and increases its extinction coefficient in the UV/VIS spectrum. (C) 1997 Elsevier Science Ltd.
