The design, synthesis and aggregation-induced emission properties of a new series of triarylborane-oligothiophene-dicyanovinyl (DCV) conjugates 4-6 (A-D-A' type molecular configuration) are reported. The optical properties of 4-6 can be modulated by judiciously varying the number of thiophene units between electron deficient boryl and dicyanovinyl units.(More)
BACKGROUND Chronic obstructive pulmonary disease (COPD) is characterized by progressive deterioration of respiratory function along with systemic effects which have a great impact on health-related quality of life (HRQoL). Classification of severity of airflow limitation in COPD does not represent the clinical consequences of COPD. Hence, combined COPD(More)
Three new triarylborane conjugated dicyanovinyl chromophores (Mes2B-π-donor-DCV); donor: N-methyldiphenylamine () and triphenylamine ( and [with two BMes2 substitutions]) of type A-D-A (acceptor-donor-acceptor) are reported. Compounds exhibit intense charge transfer (CT) absorption bands in the visible region. These absorption peaks are combination CT bands(More)
The structure and photophysical properties of a new triad (borane–bithiophene–BODIPY) 1 have been investigated. Triad 1 exhibits unprecedented tricolour emission when excited at the borane centred high energy absorption band and also acts as a selective fluorescent and colorimetric sensor for fluoride ions with ratiometric response. The experimental results(More)
Aim: To evaluate the effects of inclusion of roasted guar meal, also known as guar korma, as a partial replacement for deoiled soybean meal (SBM) in commercial broiler diets, on production performance and carcass traits of Cobb-400 broiler chickens. Materials and Methods: 1600 one-day-old Cobb-400 broiler chicks were randomly assigned into four dietary(More)
System designers of today, in view of cutting more and more costs are using integrated circuits, which are unique to their application. In the present work, the main intention is to improve the density of integration to a new height by integrating the Individual components of a typical mobile system into a semi-custom VLSI solution. Further, several error(More)
