"installed dipolar rotors into COFs which have adequate space to flip in response to electric field or heat >200°C, not affected by steric hindrance from surroundings/ orientation, can be held at ambient temperature for long time, near 400°C thermal durability... building blocks: tetrahedral 4-handed molecule, flat 3-handed molecule in which 3 dipolar rotors (1,2-difluorophenyl, DFP)/ 3 aryl groups alternately positioned around central benzene ring... discovered COF sln topology/ shape dimorphism"
