Herein, we report the synthesis of CSMs having different side chains. Hydrogen bonding, lipophilic imbalance and van der Waals interactions are imparted through the asymmetric substitution of Isoindigo. The secondary forces impact thin film morphology, and charge carrier mobility. The CSMs having van der Waals interaction further shows higher charge carrier mobility as a function of improved morphology, and increased temperature. The highest mobility of 0.15 cm2/Vs has been achieved for CSMs with van der Waals interaction.</p>10aConjugated small molecules10aIsoindigo10amobility10aOFET10aSecondary force1 aDharmapurikar, Satej, S.1 aKashmir, Arulraj, Arul1 aKumari, Tanya1 aKalalawe, Virbhadra1 aKanetkar, Maruti1 aChini, Mrinmoy, Kumar  uhttps://library.ncl.res.in/content/significance-secondary-forces-toward-improving-charge-carrier-mobility-isoindigo-based
