Exploration of pyrazine-embedded antiaromatic polycyclic hydrocarbons generated by solution and on-surface azomethine ylide homocoupling
Autor: Xiao-Ye Wang, Marcus Richter, Yuanqin He, Jonas Björk, Alexander Riss, Raju Rajesh, Manuela Garnica, Felix Hennersdorf, Jan J. Weigand, Akimitsu Narita, Reinhard Berger, Xinliang Feng, Willi Auwärter, Johannes V. Barth, Carlos-Andres Palma, Klaus Müllen
Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-7 (2017)
Polyaromatic hydrocarbons can be precisely manipulated to yield ever more complex and discrete graphene analogs, such as nanographenes. Here, the authors use azomethine ylide homocoupling to insert an antiaromatic pyrazine ring into the core of a nan

Photoresponse of supramolecular self-assembled networks on graphene–diamond interfaces
Autor: Sarah Wieghold, Juan Li, Patrick Simon, Maximilian Krause, Yuri Avlasevich, Chen Li, Jose A. Garrido, Ueli Heiz, Paolo Samorì, Klaus Müllen, Friedrich Esch, Johannes V. Barth, Carlos-Andres Palma
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-8 (2016)
Two-dimensional, self-assembled heteromolecular networks often lack functionality. Here the authors study the photoresponse of self-assembled heteromolecular networks, while controlling their positions and interfaces at an atomic level, suggesting bo
