Synthesis and properties of novel star-shaped oligofluorene conjugated systems with BODIPY cores

The authors wish to thank the EPSRC for funding. PJS thanks the Royal Society for a Wolfson Research Merit Award.Star-shaped conjugated systems with varying oligofluorene arm length and substitution patterns of the central BODIPY core have been synthesised, leading to two families of compounds, T-B1-T-B4 and Y-B1-Y-B4, with T- and Y-shaped motifs, respectively. Thermal stability, cyclic voltammetry, absorption and photoluminescence spectroscopy of each member of these two families were studied in order to determine their suitability as emissive materials in photonic applications.Publisher PDFPeer reviewe

The Role of the Special Education Teacher-Counselor in Meeting Students’ Self-Esteem Needs

Teachers of the visually impaired play a critical role in the development of affective growth within the children and youth they serve. The impact of a visual impairment on the emergence of the self, self-concept, and self-esteem must be understood before intervention strategies can be effectively employed. Each of the phases of the adjusting process in response to either social stigma or vision loss requires a somewhat different focus in counseling efforts. Whether they admit it or not, teachers are counselors—for better or worse. The article concludes with a look at some of the attributes and behaviors that promote affective growth. </jats:p
