Rational design of chiral nanoscale adamantanoids

(equation presented) Utilizing coordination as a motif, the self-organization of six ditopic and four tritopic building blocks leads to the formation of nanoscale adamantanoid frameworks.

A theoretical guideline for designing effective host materials based on 4,4'-Bis(9-carbazolyl)-1,1'-biphenyl derivatives for blue phosphorescent devices

Development of host materials is crucial for organic electroluminescent devices. In order to generalize the way to molecular design the host materials, we here present a guideline to design effective host materials for blue phosphorescent devices based on 4,4'-bis(9-carbazolyl)-1,1'-biphenyl (CBP) derivatives, comparing some theoretical parameters of seven CBP derivatives with experimental ones in terms of thermal stability, T1 energy level, and band gap. Although our computation at the density functional theory level could not reproduce the absolute values and phenomena that were experimentally obtained, theoretical relative correlations between different molecules agreed with experimental ones. Indeed, both experimental and theoretical approaches predicted that the same molecule (1,1- bis(4-(9-carbazolyl)-phenyl)cyclohexane) was viable as blue host material among the target molecules in terms of thermal stability, the T1 state with the LE character within carbazole moieties and T1 energy 3.00 eV higher than that of blue emitters. The qualitative guideline we proposed would be potentially helpful to save experimental work to design other hole- or electron-transporting materials.

Synthesis of high aspect ratio bisphenols and polycarbonates incorporating bisaryl units

Theoretical arguments linking monomer geometries to polymer fracture strengths and melt flow properties provide the rationale for design of a series of isomeric, high-aspect ratio bisphenols and new polycarbonates. An efficient synthesis of these monomers
