A new paper has appeared in Chem. Commun. on the suppression of rearrangements in polyphenylene planarization through the use of substrates with polycyclic aromatic subunits. This work is the culmination of a lot of effort from postdoc Jian He, grad student Sanyo Mathew, and former REU students Zach Kinney (now a grad student in the group), Rachel Warrell, and James Molina.
