Network-controlled unique reactivities of carbonyl groups in hollow and microporous organic polymer.

Hollow and microporous organic network bearing alkynone moieties was prepared via carbonylative Sonogashira coupling. The carbonyl groups in the network showed unusual chemical reactivities, compared with those of a model alkynone compound. The observed differences between the reactivities of alkynones in the molecule and in the network were analyzed based on the “network effect”. [ABSTRACT FROM AUTHOR]
