Summary, etc. <p>Three new terpyridine appended pyrene derivatives (<strong>Pyr-Tp</strong>, <strong>Pyr-Ph-Tp</strong>, and <strong>Pyr-Bp-Tp</strong>) have been synthesized by condensation and Suzuki-Miyaura reaction. The photo-physical, electro-chemical and thermal properties of these compounds have been investigated in detail. DFT studies have been carried out to understand the structure-property relationships at the molecular level. Synthesized fluorophores displayed high quantum yield (70-96%) of fluorescence due to triplet to singlet intramolecular energy transfer, delayed fluorescence and positive solvatochromism indicating the presence of intra-molecular charge transfer excited state. In addition, they have high thermal decomposition temperature (T<sub>d</sub>: 390-450°C), melting temperature (T<sub>m</sub>: 180-220°C) and further with suitable oxidation and reduction potentials makes them favourable molecules for OLED fabrications.</p><p> </p>
