1. Perforated monolayers: design and synthesis of porous and cohesive monolayers from mercurated calix[n]arenes
2. Reagent gradep-tert-butylphenol (mp. 98–101°). paraformaldehyde, tetralin, and KOH were obtained from Aldrich Chemical Co., Inc.
3. Since the reaction mixture is not refluxed, a modest flow of nitrogen over the reaction mixture and exiting through the condenser on top of the Dean and Stark water trap was used to facilitate the removal of water and formaldehyde during the second heating stage. It is necessary to insulate the water trap and the top of the reaction vessel; otherwise, water may not be efficiently trapped, and it must be removed for the reaction to proceed properly and reach the target temperatures. Also, with a modest flow of nitrogen throughout the heating period, the reaction mixture does not turn as dark as when only a small, positive pressure of nitrogen is used
4. Ace Glass Co. flask inlet adapter (catalog #5031) accommodates a thermometer and a nitrogen inlet
