 Synthesis and crystal structure of a
 meso-trialkynyl-[28]hexaphyrinThis is one of a number of contributions
 from the current members of the Dyson Perrins Laboratory to mark the
 end of almost 90 years of organic chemistry research in that building,
 as all its current academic staff move across South Parks Road to a
 new purpose-built laboratory.
