“…Several studies have described the excellent electrochromic, photovoltaic and electroluminescent features of D-A CPs based on fluorene and/or triarylaniline as donor units; thereby, they have been representative benchmark materials in OLEDs and OSCs [ 17 , 18 , 19 , 20 ]. However, to the best of our knowledge, there are few published works about D-A CPs containing aniline and fluorene together as donor moieties [ 21 , 22 ].…”

Abstract:A new series of two-dimensional statistical conjugated polymers based on aniline and 9,9-dihexylfluorene as donor units and benzo-or naphtho-quinoxaline/thiadiazole derivatives as acceptor moieties, possessing PANI segments as side chains, were designed and synthesized. To investigate the effects of the perpendicular PANI branches on the properties of the main chain, the optical, electrochemical, morphological and electroluminescence properties were studied. The 2D materials tend to possess lower molecular weights and to absorb and to emit light red-shifted compared to the trunk 1D-polymers, in the yellow-red region of the visible spectrum. The 1D-and 2D-conjugated polymers present optical band gaps ranging from 2.15-2.55 eV, HOMO energy levels between −5.37 and −5.60 eV and LUMO energy levels between −3.02 and −3.29 eV. OLED devices based on these copolymers were fabricated. Although the performances were far from optimal due to the high turn-on voltages for which electroluminescence phenomena occur, a maximum luminescence of 55,100 cd/m 2 together with a current density of 65 mA/cm 2 at 18.5 V were recorded for a 2D-copolymer, PAFC6TBQ-PANI.

The cracking of electrochromic materials due to aging or reiterative bending is a major problem, which noticeably degrades the performance of electrochromic devices. In this paper, a new polymer DFTPA-MA, which integrate the triphyelamine (TPA) and self-healing group, is reported in this paper. The colour of the polymer not only could switch colours between light yellow and orange red, and also have the good self-healing properties for 5 min to heal the crack about 10 μm. The polymer DFTPA-MA may hold great potential to overcome the scars generation on the electrochromic devices.
