This paper answers the conjecture of Adimurthi and Struwe , that the semilinear Trudinger-Moser functional J(u) = 1/2 integral(Omega) vertical bar del u vertical bar(2) dx - 1/8 pi integral(Omega) (e(4 pi u2) - 1) dx (0.1) (as well as functionals with more general critical nonlinearities) satisfies the Palais-Smale condition at all levels except n/2, n is an element of N. In this paper we construct critical sequences at any level c > 1/2. corresponding to a large family of distinct concentration profiles, indexed by closed subsets C of (0, 1), that arise in the two-dimensional case instead of the "standard bubble" in higher dimensions. The paper uses the notion of concentration of [2,5] developed in the spirit of Solimini  and of .
