Effect of dendron structure on the luminescent and charge transporting properties of solution processed dendrimer-based OLEDs
The energy transfer, PLQY, charge mobility, and OLED performance of blend films of first generation Ir(ppy)3-cored light-emitting dendrimers and dendrimeric TCTA-based hosts are found to be dependent on the dendrons and surface groups used.

Solid-state near infrared emitting platinum(II) complexes as either an ultrathin or singly doped phosphorescence emitting layer in hybrid white OLEDs exhibiting high efficiency and colour rendering index
Two platinum complexes PBSNND and AtFNND have been used to achieve high efficiency (EQEmax of 12.9% and 13.7%) hybrid white OLEDs with an ultrathin and singly doped phosphorescence emitting layer, respectively.

Operation mechanism of organic electrochemical transistors as redox chemical transducers
Designing OECTs to amplify chemical redox reactions reliably requires: (1) separating reaction from the OECT (2) operating the OECT potentiometrically (3) utilizing non-polarizable gate electrode (4) maximizing transconductance of channel material.

Tailoring oxygen evolution reaction activity of metal-oxide spinel nanoparticles via judiciously regulating surface-capping polymers
It is discovered that the negative effects on OER activity caused by the stabilization of NPs with surface-capping polymers can be mitigated by decreasing the grafting density or increasing the hydrophilicity of the polymer chains.

About this collection
During his career, Seth Marder has had tremendous impact as a scientist, as a mentor, as a teacher, and as the founding Editorial Board Chair for Materials Horizons. He has not only made significant contributions to the fields of chemistry and materials science and engineering, but he also greatly impacted students and young scientists from all around the world as a teacher and mentor of science at all levels. With this themed issue and accompanying web collection, we would like to celebrate his commitment to the community and in particular his support towards inclusion and diversity over the last decades, as well as Seth’s strong commitment to the journal itself in his long-standing role as Editorial Board Chair of Materials Horizons over the last 8 years, which was conceived outside of the traditional mold.
On the occasion of Seth’s 60th Birthday, we hope that you will join us in celebrating his achievements and continued contributions to the field by enjoying these articles published in this Festschrift issue of Materials Horizons Guest Edited by Zhenan Bao (Stanford University, USA), Jean-Luc Brédas (University of Arizona, USA), Thuc-Quyen Nguyen (University of California Santa Barbara, USA), and Mark Thompson (University of Southern California, USA), as well as the articles in the web collection, which includes additional contributions from across RSC journals from Seth’s friends and colleagues.
