Interpenetrated metal-organic frameworks (MOFs) are often observed to show lower porosity than their non-interpenetrating analogues. It would be highly desirable if the interpenetrated MOFs could still provide high stability, high rigidity, and optimal pore size for applications. In this work, an asymmetrical tricarboxylate organic linker was rationally designed for the construction of a copper(II)-based microporous MOF with a twofold interpenetrated structure of Pt3O4 topology. In spite of having structural interpenetration, the activated MOF shows high porosity with a Brunauer-Emmett-Teller surface area of 2297 m2g-1, and high CO2 (15.7 wt% 273 K and 1 bar) and H2 uptake (1.64 wt% 77 K and 1 bar). Playing with symmetry: A C2-symmetric tricarboxylate organic linker with elongated arms has been developed for the construction of a twofold interpenetrated metal-organic framework. Despite its structural interpenetration, the framework exhibits high surface area and high adsorption capability for CO2 and H2 (1.64 wt% at 77 K and 1 bar).

Disclosed herein are ambipolar host compounds represented by formula (I): (I), wherein: a) at least one of the R1, R2 and R3 groups is an optionally substituted carbazole group, and the remaining of R1, R2 and R3 are independently selected from hydrogen, halogen and a C1-20 organic group; b) R4 is an optionally substituted alkyl group, an optionally substituted heteroalkyl group, a substituted aryl group comprising at least one heteroatom in the substituent, or an optionally substituted heteroaryl group; and c) Y is selected from, and, wherein R5 is an optionally substituted aryl group, an optionally substituted heteroaryl group, an optionally substituted alkyl group or an optionally substituted heteroalkyl group, and wherein R6 is hydrogen, an optionally substituted aryl group, an optionally substituted heteroaryl group, an optionally substituted alkyl group or an optionally substituted heteroalkyl group. The compounds can be used in OLED devices.
