that of the compound with an electron-withdrawing group on the carbazole framework was positive. The electrocatalytic oxidation activities of the nitrocarbazole compounds were investigated through cyclic voltammetry and controlled potential electrolysis at room temperature. The electrocatalysts showed excellent selectivity for p-methoxybenzyl alcohol, converting it to the corresponding aldehyde through
bandgaps of at least 2.93 eV for the fluorene‐based and 3.07 eV for the carbazole‐based polymers. The amino‐functions allow to tie semiconducting CdTe nanocrystals (NCs) and to synthesize a series of composites with CdTe NCs. Moreover, tuning the emission color over a wide range by tying these CdTe NCs results in a facile preparation of organic–inorganic semiconductor composites with emission colors “à

The invention relates to a “push-pull” type compound, used for manufacturing polymer materials having both electrical conduction and photochromic properties, which responds to the general formula A-X-R in which:
A is an electron acceptor group;
X is a group having a π-conjugated system and forms a photochromic group with A; and
R is a polymerizable electron-donor group that is chosen among the carbazole group and the groups derived from the carbazole group by substitution, and which is linked to X by the nitrogen atom of the carbazole group.
The invention also relates to an electroconducting and photochromic polymer material, obtained by polymerization of this compound.
Applications: optoelectronics, signal processing, data storage, etc.

carbazole-based organic compounds (Cz-2Ph3F 6FDA and Cz-2TPA 6FDA) with different ratios of electron-donating and electron-withdrawing units were designed and synthesized. An ITO/Cz-2Ph3F 6FDA/Al device was fabricated and presented binary rewritable memory behavior, whereas the as-fabricated ITO/Cz-2TPA 6FDA/Al device exhibited ternary rewritable memory behavior. The electrical conduction behaviors of memory devices
