Several elastic polymer sheets of poly(methyl methacrylate) (PMMA) blended with CT complex between different derivatives of 1,8–naphthalimide fluorescent dyes and p-chloranil (CHL) acceptor were prepared to use in solar cells. The morphology of one of these polymer sheets (PS1c) had numerous clearly visible openings having asymmetrical structures. These openings have different sizes, shapes, and depths. These openings increased the S-parameter value for this polymer sheet compared with the others. [Display omitted] •Several derivatives of 1,8–naphthalimide fluorescent dyes were synthesized.•These dyes were complexed with CHL acceptor via CT interaction.•CT complexes were dispersed in PMMA to fabricate the polymer sheets.•The polymer sheets were characterized by PAL and PADB techniques.•The polymer sheets show a good semi-conductive property. The present work aimed to prepare elastic polymer slices that have semiconductors properties for use in solar cells based on charge transfer (CT) complexation. For this purpose, first six derivatives of 1,8–naphthalimide fluorescent dyes were synthesized. Secondly, the synthesized fluorescent dyes were complexed with p–chloranil acceptor via CT interaction in methanol solvent. The obtained CT complexes were dispersed in poly(methyl methacrylate) (PMMA) matrixes using methylene chloride solvent at room temperature. The obtained polymer sheets were characterized by several spectroscopic and physicochemical techniques, such as IR and UV–vis spectroscopies; and SEM technique. The microstructural and morphological changes occurred in the sheets of the PMMA matrix blended with the CT products were observed using the positron annihilation Doppler broadening (PADB) and the positron annihilation lifetime (PAL) techniques. Finally, the photostability and the direct current (DC) electrical characteristics as a function of the temperature for the CT products dispersed in PMMA matrixes have been studied.
