In this review, recent advances that exploit the intrinsic emission of organic materials for reversibly modulating their intensity with applied potential are surveyed. Key design strategies that have been adopted during the past five years for developing such electrofluorochromic materials are presented, focusing on molecular fluorophores that are coupled with redox-active moieties, intrinsically electroactive molecular fluorophores, and unconjugated emissive organic polymers. The structural effects, main challenges, and strides toward addressing the limitations of emerging fluorescent materials that are electrochemically responsive are surveyed, along with how these can be adapted for their use in electrofluorochromic devices.

The study examined career choice and academic programmes among senior high school students in the Ashanti Mampong Municipality. The study was guided by three research questions and three hypotheses. The study used the descriptive cross-sectional survey design with a quantitative approach. Multi-stage sampling procedures (purposive, proportionate, and simple random sampling) were used to select a sample of 336 respondents for the study. The instrument used to gather data was the questionnaire. The data was analysed using means and standard deviation while hypotheses were tested using an independent sample t-test. Results revealed that environmental factors, institutional factors, and personal characteristics influenced students' career choices and academic programmes. The study revealed that there was no significant difference in the perception of male and female students regarding the environmental factors that influenced their selection of career choice and academic programme. The study further revealed gender differences in institutional factors when making decisions about their career choice and academic programme. The study again revealed no gender difference in the mean score of students’ perception regarding their personal characteristics that influenced their choice of career and academic programme. Based on these findings, it was recommended that educators and school counsellors should focus on parents’ socio-economic status when counselling students on career choice and academic programmes.

“…However, despite their applicability, there is only a handful of reports on materials that can exhibit EC and EFC properties simultaneously. 29,[39][40][41][42][43][44][45][46] In this regard, in this present work, we report two triazine-based D-A three-dimensional (3D) conjugated covalent polymeric frameworks (CPF1 and CPF2 as shown in Fig. 1) fabricated by coupling a thiophene (donor) unit with a triazine ring (acceptor) through a phenyl ring spacer, and we then studied their EC and EFC properties.…”
