WebAnswer: Boron itself has only 6 valence electrons. By octet rule, boron has an ability to accept one lone pair electron from Lewis base such as ammonia. FYI, a Lewis acid is an electron-deficient compound having ability to accept lone pair electron; a Lewis base is an electron-riched compound or... WebElectron-riched carbazole moieties on the peripheral side chains of fluorene unit significantly reduce the first oxidation potential and increase the highest occupied molecular orbital energy levels of PCFBTs. Increase of hole injection and transport ability was achieved in PCFBTs. Among them, PCFBT shows a maximum luminous efficiency of 0.7 … WebElectron rich: The type of hydrides that have more electrons than required for bonding is called electron-rich hydrides.
