A Fully Conjugated Planar Heterocyclic [9]Circulene
Journal of the American Chemical Society, 2020Fully aromatic [n]circulenes have only been known to encompass up to eight aromatic rings (n = 8), with no reports of endeavors in the synthesis of higher-order analogues (n > 8). Herein we present the first [9]circulene, formally a diazatrioxa[9]circulene, along with a tetrahydro-diazatetraoxa[10]circulene.

Evidence for Fully Conjugated Double‐Stranded Cycles
Chemistry – A European Journal, 2011AbstractA chain of circumstantial evidence for the existence of the first fully conjugated, double‐stranded cycles is presented. The products have the structure of the belt‐region of fullerene C84 (D2) and carry either four hexyl chains or four phenyl groups. The unsubstituted parent cycle is also presented.

Fully Conjugated and Soluble Polyazomethines
Macromolecules, 1997Fully conjugated and soluble polyazomethines were synthesized by the polycondensation of aromatic dialdehydes with two kinds of diamines having a tetraphenylethylene structure, cis- and trans-1,2-b...

25th Anniversary Article: No Assembly Required: Recent Advances in Fully Conjugated Block Copolymers
Advanced Materials, 2013 Fully conjugated block copolymers have emerged as promising materials that combine semiconducting properties with the ability to self‐assemble at the nanoscale. The convergence of these two features has tremendous implications for a number of fundamental

Point defects in fully conjugated polymers
Journal of Applied Physics, 1976Formation thermodynamics is examined for two different types of point defects which interrupt conjugation in polydiacetylene crystals: bond-alternation and orbital-flip defects. While bond-alternation defects in these polymers are analogous to previously investigated radical pair defects in the polyenes, much lower equilibrium concentrations are ...

Fully-Naphthalenoid Hydrocarbons and their Conjugation Modes
Polycyclic Aromatic Compounds, 1994Abstract A fully-naphthalenoid hydrocarbon (FUN) is a benzenoid hydrocarbon whose all π-electrons can be (formally) grouped into disjoint naphthalene-units. The cyclic conjugation in FUNs is studied by means of the energy-effects of their various cycles.
