Conjugated microporous polymer

Conjugated microporous polymers (CMPs)^[1][2] are a sub-class of porous materials, related to structures such as zeolites, metal-organic frameworks, and covalent organic frameworks, but amorphous in nature, rather than crystalline. CMPs are also related to conductive polymers because these porous networks can exhibit extended conjugation.

Uses

Initial studies on these porous materials related mostly to gas sorption, but more recent work has focused on their potential in terms of catalysis,^[3] for example in the form of 'metal-organic CMPs',^[4] and also for light harvesting,^[5] taking advantage of their highly conjugated nature. Surface areas in CMPs can exceed 1000 m²/g in many cases, although related porous aromatic frameworks,^[6] which lack extended conjugation, can have much higher surface areas of more than 5500 m²/g. A further advantage claimed for CMP materials is the ability to derivatize them with a wide range of functional groups.^[7]
