Alternating Copolymers Incorporating Dithienogemolodithiophene for Field-Effect Transistor Applications [PDF]

, 2014
We report the synthesis of an electron-rich fused dithienogemolodithiophene monomer containing straight chain tetradecyl solubilizing groups. Copolymers were prepared with four different electron accepting monomers of varying reduction potential.

Rational Design of Donor‐Acceptor Oligomers for Enhanced Charge Separation

Advanced Physics Research, Volume 5, Issue 4, April 2026.
How can molecular symmetry be broken to maximize photoinduced charge separation? Through first‐principles analysis of 22 DTP‐based donor‐acceptor ternary oligomers, this work establishes that combining architectural asymmetry with site‐selective acceptor fluorination creates an ideal electrostatic landscape for frontier orbital segregation.

Modular Donor‐Acceptor Diradicaloids Based on an Electron Deficient N‐Heteroacene Acceptor

Small, Volume 22, Issue 20, 7 April 2026.
This work presents a modular approach to donor‐acceptor‐donor (D‐A‐D) diradicaloids that show systematic evolution of their energy gaps, singlet‐triplet splittings, and diradical character (y). The correlation of (opto)electronic, spin, and magnetic properties with high‐fidelity theoretical investigations provides clear connections between the degree ...

Implementation and benchmark of a long-range corrected functional in the density functional based tight-binding method

, 2015
Bridging the gap between first principles methods and empirical schemes, the density functional based tight-binding method (DFTB) has become a versatile tool in predictive atomistic simulations over the past years.

Tetraaza[7]–[15]helicenes Synthesized by Two‐Step Strategy: Length‐Controlled Chiral π‐Systems Exhibiting Amplified Circularly Polarized Luminescence

Angewandte Chemie, Volume 138, Issue 14, 27 March 2026.
A modular two‐step strategy provides tetraaza[n]helicenes (n = 7–15) as a homologous series with tunable photophysical and chiroptical properties. Extension beyond n = 11 induces pronounced through‐space π–π interactions, narrowing the energy gap and amplifying circularly polarized luminescence.
